Currently, ZTT new developing 220kV overland power cable has successfully passed the“New products appraisal meeting”organized by China Electricity Council.

ZTT 220kV XLPE power cable technology appraisal meeting has caused the HV power cable industrial expert’s wide concern. And all the experts have agreed that ZTT new technology of 220kV XLPE power cable with great length and section has been superior to national standard and reached to international advanced level.

Duirng the new product developing period, ZTT technological team has overcomed the difficult problem like large cross-section split conductor water resistant technology, delivery with great length, insulation eccentricity and proceeded the project design, simulated analysis, experimental study to put the submarine cable production technologies with great waterproof and great length into super HV overland power cable production.
